You can delete a collection and associated metadata, if the following criteria are all true:

  • Your user account has the group administrator role.
  • You own that collection. For information on the Own permission level, refer to About Permission Levels.
  • That collection is empty.


To delete a collection: 

  1. Log in as described in Logging In via the GUI. The Dashboard appears.
  2. Browse for content as described in Browsing for Data via the GUI. The Browse page appears.
  3. Navigate to and right-click the collection you want to delete. Click View Details. The Collection page appears.
  4. On the Collection page, click the delete icon (The delete icon.). A message appears, prompting you to confirm the deletion.
  5. Click OK. By default, the system performs a soft deletion. The system retains this collection for two years and then permanently deletes it. Only DME system administrators can perform immediately permanent deletion.

To delete a non-empty collection as a group administrator, consider using the CLU command with the recursive (-r) option, as described in Deleting a Collection via the CLU. To request deletion of data you do not own or older data, contact NCIDataVault@mail.nih.gov.
